Development of a digital model for cooling efficiency of metal working fluids in machining
Abstract
In this manuscript, cutting temperature generated in machining process, it’s sources and dissipation directions are studied. Energy consumption in metal cutting process and metal working fluids have taken as an object of the study. Moreover, the effect of metal working fluids in heat dissipation process and the importance of their cooling capacity is theoretically researched. As a result of the study, dependence model of temperature gradient between cutting face and fluid on fluid’s density and viscosity is mathematically developed. The developed digital model gives an easy way to predict metal working fluid’s cooling capacity before it’s use. It can be concluded that the reduction cutting fluids’ viscosity causes an increase in the cooling capacity of the fluids while high dense fluids show a better cooling capacity.
